Long-acting reversible contraceptive (LARC) methods, such as the intrauterine device and implant, are highly effective but used by less than 10% of US women. The objective of our study was to improve LARC interest by enhancing clinic counseling.

A quality improvement methodology was used to evaluate intrauterine device service delivery in 3 Chicago Title X clinics. To address identified barriers, we developed a theory-based iOS application (app) for patients to use in the clinic waiting room using human-centered design. The final prototype was tested in a randomized controlled trial in a Title X clinic with sexually active females (79% African American) under age 30 years. Our sample of 60 was chosen to detect an increase from 10% (baseline) to 45% (app intervention) in the proportion of patients expressing interest in discussing a LARC method during their clinic visit with 80% power and two-sided α = 0.05. After completing demographic and baseline knowledge questionnaires, participants were randomized 1:1 to intervention (app) or standard care arms. App users also completed a posttest. Our primary outcome was expressed interest in discussing a LARC method during the clinic visit. Secondary outcomes were contraceptive knowledge and LARC selection.

App testers (n = 17) preferred interactive, visually appealing design and video testimonials. In the pilot randomized controlled trial (n = 52), app users had a significantly higher knowledge of contraceptive effectiveness (P = .0001) and increased interest in the implant (7.1-32.1%, P = .02) after the intervention. Users were highly satisfied with the app. Staff reported no problems using the app in the clinic.

Use of a theory-based counseling app offers a novel method to optimize wait time while minimizing clinic flow disruption. Preliminary data demonstrate that app use was associated with improvements in patients’ contraceptive knowledge and interest in the implant.
